STICKNEY, OF HILLSIDE, NEW JERSEY,ASSIGNOB TO UNDERWOOD EL- LIO'IT FISHER COMPANY, OF NEW YORK, N. Y., ACORPORATION OF DELAWARE TYPEWRITING MACHINE Original No. 1,679,951,dated August 7, 1928, Serial No. 40,741; filed July 1, 1925. Applicationfor rei s filed August a, 1923. Serial No. 298,587.

This invention relates to f'ronbstrike typewriting machines equipped fortyping upon multiple-ply webs, the same being either fanfolded orconsisting of loose plies.

These plies are usually interleaved with sheets of carbon, which areusually long enough to cover only one or two forms. The carbons arestripped from each form after it is typed, and shifted to the succeedingform on the web.

WVhere many copies are being manifolded, a; difliculty arises inround-platen typewriters, when it is desired to strip the carbons fromthe typed the web, because the carbons stick 'to the plies of web wherethey bend around the platen, a snubbing action taking place, that is,thecarbons having the effect of one bind ing upon another as it isattempted to pull them all back around the under side of the platen, asby pushing back the carrier to which all the carbons are attached attheir rear ends. The carbons are difiicult to strip or shift, and areapt to become torn. To avoid this difliculty, it has been the practiceto displace the platen upwardly to permit .the composite web to bestraightened out, so

that the carbon-carrier can strip the carbons easily back to thelr newpositions; whereupon the platenhas been depressed to typing position.This makes necessary a substantial inexpensive,

and expensive reconstruction of the typewriter-carriage and theplaten-connections, and to provide expensive and bulky appurtenances.

An object of the invention is to avoid the delay and trouble that isusually experienced in. round-platen typewriters of displacing theplaten upwardly for this purpose, that is, toenable the carbons to bestripped successfully without displacing the platen, and in fact whilethe composite web remains looped around the platen, and to effect thisresultby means of simple, inexpensive devices whieh are readilyattachable to a standard typewriting machine, thus avoiding thenecessity of partially rebuilding the same.

An object of the invention is to provide an light device for strippingthe carbons, of such a character that the stripform to the fresh form onping device and the web-presenting devices can be attached directly tothe typewriting' machine, or to the. carriage thereof, with little or noalteration therein, and may be easily and rapidly manipulated.

It is one of the features of this invention many carriers as there arecarbons, and each carrier can move independently of all the.

others. It is within the scope of the invention, however, to'attach twocarbons to each independently movable carrier in some cases. After aform is typed, the outermost carbon may be stripped from the typed formtothe next form, and therefore no longer binds upon the inner carbons.Said outer carbon strips easily and readily, because there is no carbonor sheet binding thereon. Then the next outer carbon may be strippedfrom the typed form to the succeeding form, and moves easily, becausethe outer carbon has been shifted back from around the platen.

Then the third carbon may be shifted in like manner, and then thefourth, and so on; each carbon shifting readily because it is not boundby any other carbon.

t will thus be seen that the carbons may be stripped one after another,beginning with the free carbon until they are all stripped.

This overcomes the difficulty heretofore experienced of the binding oftaut carbons upon one another as it was attempted to pull them aroundthe platen. In the present invention there need be no binding and nodifliculty.

If two adjacent carbons are attached to one carrier, they can in somecases be stripped successfully, because the binding of the outer uponthe inner of the two carbons is not sufficient to prohibit the strippingoperation.

According to the preferred form of practicing the present invention,when the com posite web stands looped around the platen at thecompletion of the typing of a form,

the leading end of the web may be clamped or fastened to'the machine,preparatory to stripping the carbons. Thereupon the feedrolls are castoil from the platen, thus releasing the web, and the outermost carbon ispulled back around the platen and retracted to position in register withthe next form on the web. It will be understood that since no carbonsurrounds said outermost carbon, there is nothing to bind upon it, or tohold it against the work-plies, and it will slip readily back around theplaten. Then the next carbon (which has in its turn become the outermostone) is stripped back easily, since there is no exterior carbon-sheet tobind thereon. These carbons slip back to a point where their leadingends are under the platen, so that there is no loop, and no binding orsnubbing effect of a stripped carbon upon the unstripped carbons.Moreover, the stripped carbons are not under tension, inasmuch as theyare arrested by stops atthe completion of the stripping operation. Thestripping may proceed, stripping one carbon after another, until theyare all stripped.

' Then the leading end of the web may be advanced to bring the bottomedge of the just-typed form up to a web-severing knife; a severing gagebeing provided for the leading edge of the web.

Each stripper or carbon-carrier is preferably in the form of atransverse bar having at its ends bent-up ears; and in these cars thereare journaled transverse horizontal rock-shafts, each rock-shaftcarrying pinions at its ends. The pinions mesh with station ary racks, apair of which extends upwardly and rearwardl from the rear end of theusual paper-table and carriage of the Underwood standard typewriter.Hence each stripper moves back and forth in parallelism.

The strippers may be moved by hand, and preferably they are providedwith fingerpicces at alternate sides of the machine, so that the lefthand may move the outer strip, and then the right hand may move thenext, and the left hand the next, and the right and the next, and so on,so that the stripping may be readily effected.

Preferably the first stripper is connected by individual springs witheach of the remaining strippers, all of these springs being tensioned atthe operation of retracting the first stripper, and thereafter advancingor tending to advance the remaining strippers,

so that in "some cases the strippers will be come self-retracting, solong as the first stripper is held back against its stop.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a diagramatic sectional side elevation, illustrating thecompletion of the typing of a form, the leading end of the 1111921113 Ofan axle form having been advanced to a strippergage. In this and otherviews, the points of division between each printed form and the next areindieatedby short dashes inter secting the web.

Figure 2 is a sectional central elevation on a larger scale, showing theleading end of the web as having been clamped, the feedrolls released,and all of the carbon-strippers retracted.

Figure 3 is a view similar to Figures 1 and 2, but showing a laterstage. At'Figure 3 the web is shown as advanced to the websevering gage,and the next form, with the interleaved carbons, is in position to begintyping thereon. At this figure the leading form is shown as being tornolf by the knife.

Figure 4 is a rear or bottom View of the strippers and racks.

Figure 5 is a front view of the platen and platen-frame, with thedelivery table, websevering knife, etc., and showing the leading end ofthe first form set up against the stripping and under the clips, to holdthe work-web fixed while the carbons are being stripped or shiftedbetween the workplies.

Figure 6 is a semi-perspective view, looking rearwardly and downwardlyupon the platen and the stripping mecl1anism,-showing the strippers intheir retracted positions.

Figure 7 is a cross-sectional View corre sponding to Figures 4 and 6,and showing the racks in section, also a stripper, with a pinion-shaftand carbon-blade. This View incidentally shows the stripper in invertedposition, because it is placed below Figure 6; but it will be understoodthat if placed above Figure (5 it would appear withthe carbonblade atthe top and the pinion-shaft at the bottom of the view.

In the Underwood standard typewriting machine, types 10 strike againstthe front side of a platen 11, which is 'journaled by in a platen-frame,which comprises ends 13 joined by a rear papershelf 14, which inclinesdownwardly and forwardly and-curves under and up in front of the platen.This platen-frame is usually shiftable up and down upon a paper-carriage15, which is guided upon tracks 16 supported on the framework of themachine 17.

A. multiple-ply web 18, either fan-folded or consisting of loose plies,is led up from a source of supply, and passed forwardly over a guide-bar19, between side guides 20, adjustable along said bar. The bar may bemounted by means of brackets 21 011 the rear ends of two rack-bars 22,23, which extend dowrnvardly and forwardly to the papershelf 1 1. Attheir lower or front ends the rack-oars are connected by atransversetierod 24; the parts 19, 21, 22, 24 and 25 forming a ri idframe. It will be seen that 25 eonsists'of a pair of brackets Which arerivavoid overweighting the carriage; but it is obvious that a tablemaybe supplied if desired.

This rack-frame is detachably mounted upon the typewriter-carriage. Forthis'purpose split-pointed spring-studs 27 are inserted in socketsformed in ears 28 bent up from a bracket 29. which is secured by screws30 upon the rear bar of the typewriter-carriage 15. In order to take therack-frame off the. machine, it is only necessary to pull the splitspring-studs 27 out of the sockets. These spring-studs tend to open, andhence they bind in the sockets. Other means for detachably holding therack-frame upon the typewriter may be provided.

Interleaved with the web-plies, which are indicated at 31, Figure2, arecarbon-sheets 32, theleading ends of which are shown at 32, Figure 2, at32*, Figure 1, and at 32, Figure 3. The rear ends of the carbons areattached to blades 33 secured by usual'dowel pins (not shown) upon heads34, Fi ure 7, and are withdrawn from and replaced upon said heads bymeans of finger-pieces 35, in.

the usual way for the usual purpose of loading the carbons. Theblades insection have an echelon relation at Figure 2, the outermost carbon beingconnected, to the first or rearmost blade, the next carbon to the nextblade, and so on, the innermost carbon being connected to the lowestblade, which is the nearest to the platen, and which is the last to beretracted.

The heads 34 are secured alternately upon opposite ends of carrier-bars36, which extend horizontally from right to left, overlying the racks22, 23, and havingat their,

ends bent-down ears 37, 38, fitting over the racks, which serve asguides and supports or as tracks for these carbon-strippers. The cars37, 38 are continued downwardly to form bearings for the ends ofrock-shafts 39, which extend across the machine, each shaft having fixedupon its ends pinions 40, 41, the pinions 4O meshing with the rack 22,

, and the pinions 41 meshing with the rack 23.

The rack andpinions make a compact, light structure, and are employed tomsure that the individual movements of each carbonstripper shall be inparallelism, and that it V shall not :bind or skew, even though thestripper is moved by means of its handle 42 at only one end thereof.

'The strippers, in their retracted positions at Figure 2, lie one aboveanother upon the racks or tracks, and the carbons extend downwardly andforwardly therefrom, each carbon being usually about the length of twotyped forms, and terminating at 32.

At the completion ofthe form-typing operation, the lower end of thefirst form stands a little below the printing line, and at the pointmarked 43, Figure 1; and the composite web of work-plies and carbonsstands looped around the platen. The leadingends of the web are set upagainst a gage 44, which may be adjusted up and down upon and along arearwardly-inclined work-shelf 45, havinga slot 45 for this purpose, andmounted atthe delivery'side of the platen 11. This gage is secured whereadjusted by a thumb-screw 46. Upon the gage is provided a pair of clips47, which may be forced down to clamping position by means of a handle48. This handle is shown in released position at Figure 1, and inclamping position at Figure'2. It is fixed upon a rock-shaft 49, havinga fiat 50, which, when the handle is depressed, permits the springclips47 to rise and free the work-web.

lVhen the typing of a form is completed, as at Figure 1, the handle 48is raised, Figure 2, to cause the rock-shaft 49 to force down the clips47 upon the front corners of the leadingv end of the Web, thereb holdingthe same stationary during the carbon-stripping operation. The next stepis to release the feed-rolls 51, which usually run upon the car in itsupward movement. At this time the leading edge of the stripped outercarbon reaches the retracted position seen at 32,-

Figure 2, which is just under the bottom of the platen, so that thisouter retracted carbon has no purchase to bind upon orsnub the innerunretracted carbons. Moreover, said carbon-earrien36 is arrested by astop 54, and'hence there is no pull upon the carbon, and consequently nobinding thereof upon the inner carbons, which still remain unretracted.The stop 54 may bc adjusted backwardly and forwardly along the rack 22,and secured by a clamping screw to accommodate different lengths ofcarbons and forms. The next carbon-holder 36 n'lay be thrust backwardlyby means of its handle 42, thus stripping the second carbon from thetyped form, as this is now the outermost carbon, so far as the platenisconcerned; and this carbon-stripper or carrier may he thrust backwardlyand upwardly against the first retracted cabon-carrier 36. Then the nextcarbon is retracted by means of a handle 56 upon its carrier, and thenthe fourth carbonby means of a handle 57 on its carrier. It will be seenat Figure 4 that these handles are alternately at opposite sides of themachine, permitting the use of the right and left hands alternately,thus saving time and labor in stripping the carbons.

If desired, adjustable tension-springs 58 may be secured at their rearends to brackets 59 upon the rearmost carbon-carrier, and in dividuallyconnected at their forward ends to the several remaining carbon-carriers36. These springs may be tensioned by the backward, pressure of thethumb upon the fingerpiece 52, when retracting the first carbon carrier.The springs which are connected to the nextcarbon-carrier will pull thesame rearwardly' Thereupon both of the-retracted carbon-carriers may beheld back by means of finger-piece 42. The springs will then pull backthe third carbon-carrier, and all three retracted carriers may be heldback by finger-piece 56 Then the remaining springs will retract theremaining'carboncarrier. However, the springs may, if desired, be mademuch weaker, so as to have .merely the efiect of assisting in thepulling back of the carbon-carriers; that is, the springs may be made toco-operate with the fingers of the operator in elfecting the retractionof the successive carbons. The springs may be adjusted to vary theirstrength as desired.

Then the carbons are all retracted, their leading ends all stand at theposition 32, just under the platen at Figure 2. The leading web-form',whose lower end is indicated at 43, is then advanced by pulling the sameup by means of its leading end, after the clips 47 have been released bypulling down the handle 48. Then said leading endof the typed form islifted out from under the clips and advanced by hand against a gage 60,which is adjustable along astaff 61 extending backw-ardly from the topof the gage 44, the gage 60 being secured by a thumbscrew 62. At Figure3 the leading end of the typed form is shown as adjusted to' this .gage60, thus bringing the succeedlng form (whose bottom end is indicated at63". Fig ure 3) to position to receive the first line of typing, thecarbons at 32,Figure 3, being now just above the printing line. Beforebeginning the typing of this second form, the first form may be tornoff, by the aid of knife 64 asseen at 69, Figure 3. The feedrolls 51 maybe then restored from their released positions to their effectivepositions, asseen at Figure 3, and the typing of the second form mayproceed.

It will be understood that the rack-frame may be detached by pulling outthe studs from the sockets, and together with the strippers thereon andthe composite web, said rack-frame may be temporarily laid aside, whileanother rack-frame having its own set of carboncarriers through whichanother web is threaded may be attached to the machine by inserting thestuds in the sockets. Thus the machine is readily adapted to performwork upon diflerent composite'webs selectively, without disconnectingany web from the carbon-carriers through which it isthreaded, therebymeeting a well-known requirement in this art.

The delivery work-shelf 45 can be swung forwardly anddownwardly upon ahinge at 63, thereby forming a convenient table, and also givingconvenient access to the leading end of the work-web when it is desiredto load the carbons or insert the blades with their attached carbonsbetween the plies of web. The blades may thereupon be attached to thecarbon-carrier heads by inserting the usual dowels in the usual sockets.This work-shelf 45 is hinged to a frame which includes standards 64having flanges or feet 65 detachably mounted by screws 66 upon saidplaten-frame, and also including an inclined plate 67, to which theknife 64 is attached, and supporting flanges 67 The folds of the websmay be split by blades 68 on' the ends of the carbonstrippers.

It will be noted that one feature of the invention is the provisionof acompact stripper foreffecting the necessary shifting between theweb-plies and the carbon in linespace direction. novel compact stripperto form one of a set of independently-movable strippers or carriers, andtheir compactness may conduce to economy of carbon, since the excess inlength of the longest carbon over the shortest isnot very much, inasmuchas the distance from the top stripper to the bottom stripper (Fig- 'ure6)'is kept at a minimum by the use of the compact strippers. The compactstripper is not limited to this use, however, and it will be seen thatthe stripper has the form of a sheet-carrier and that it is renderedcompact by forming it in the shape of a cross-beam which extendshorizontally from one track, at one side of the web, to the other trackat the other side of the web, and has bearings upon both tracks, whilethe crossbeam, bar, or truck 36 depends upon its pinions 40 and shaft 39to maintain it in parallelism with the platen by co-operatioh withstationary racks 22, with which the pinions mesh. The pinions, whichoccupy little space, travel with the truck, while the racks, which arevery long, remain stationary or non-traveling.

The relative stripping movement is effected between the plies ofwork-web and the interleaved carbon with the platen in normal printingposition.
